I know this is the Windows forum but the reason I am posting HERE is that the wealth of information here concerns virtual machines and isn't really matched by other parts of the forum. I've accessed my Windows 7 partition but would now like to branch back into Linux territory. I was hoping to hear from your experiences, tips & tricks, etc. with virtual machines, both with Windows 7 and other OSes through VMWare Fusion. Even though I have 4 GB of RAM, should I utilize a 64 bit VM or is it worthless since the VM isn't given enough? Which Linux builds will give me the most drivers and performance otb? Has anyone tried Crunchbang! or Mint in VM?
